Help regarding bin and tif file usage

I have a code that works fine with bin file that is .bin file but I have to use it with an .tif file. Can anyone help me with this

N=2408;M=3199;
lambda=500*10^(-9);
h=0.050;
z=0.1;
z0_start=0.001;
z0_end=0.003;
z0_step=0.0002;
fid=fopen('myBin.bin','r');
hologramO=fread(fid,[N M],'double');
fclose(fid);
S=round((z0_end-z0_start)/z0_step);
reconstructionO=zeros(N,M,S);
for ii=1:S
    z0=z0_start+ii*z0_step;
    area=z0*h/z;
    prop=PropagatorS(N,M,lambda, area, z0);
    recO=abs(IFT2Dc(FT2Dc(hologramO).*prop));
    reconstructionO(:,:,ii)=recO(:,:);
    imshow(rot90(abs(reconstructionO(:,:,ii))),[]);
    colormap(gray)
    pause(0.01);
    fid=fopen(strcat('b_reconstruction_z0_',int2str(z0*100000),'_area_',int2str(area*100000),'um.bin'),'w');
    fwrite(fid,recO,'real*4');
    fclose(fid);
    p=recO;
    p=255*(p-min(min(p)))/(max(max(p))-min(min(p)));
    imwrite(rot90(p),gray,strcat('b_reconstruction_z0_',int2str(z0*100000),'_area_',int2str(area*100000),'um.jpg'));
end

In line 8 instead of reading data from a .bin file I have to read it from a .tif file. How should I change the code.

imread will probably already be enough. You are currently reading in a file with one format, and you want to switch to reading a file with another. You need to make sure the variable that comes out is the format you expect. imread will probably already return the values you need, although it is possible you need to rescale the data.

Without a better description of your data definition it is hard to tell. This is something you need to figure out on your own.

... if you had posted your question to MATLAB Answers then I could have responded...)
